diketahui : p = 5 2/7 , q = 1/4 dan r = 3 1/2. nilai dari p-q:r adalah

p = 5 2/7 = 37/7
q = 1/4
r = 3 1/2 = 7/2
p-q:r = 37/7 - 1/4 : 7/2
= 37/4 - 1/4 × 2/7
= 37/7 - 2/14
= 74/14 - 2/14
= 72/14
= 36/7
= 5 1/7

p=5 2/7=37/7
q=1/4
r=3 1/2=7/2
p-q:r
37/7-(1/4:7/2)
37/7-(1/4x2/7)
37/7-(2/28)
37/7-2/28
148/28-2/28=146/28=73/14= 5 23/14
